Graph y=tan(x/2)
Problem
Solution
Identify the parent function and its properties. The function is a transformation of
y=tan(x) which has a period ofπ and vertical asymptotes atx=π/2+n*π Determine the period of the transformed function. The period
P is calculated by dividing the standard period of tangent by the coefficient ofx
Find the vertical asymptotes by setting the argument of the tangent function equal to the standard asymptote locations.
For
Identify key points within one period
(−π,π)
Whenx=0 y=tan(0)=0
Whenx=π/2 y=tan(π/4)=1
Whenx=−π/2 y=tan(−π/4)=−1 Sketch the graph by plotting the center point
(0,0) the key points(π/2,1) and(−π/2,−1) and drawing the curves approaching the vertical asymptotes atx=±π
